Barry Allen and a twin brother were born two weeks late, to Henry and Nora Allen in the small midwestern town of Fallville, Iowa. The lateness of Barry's birth only foreshadowed his bad habit of always being late.
Barry grew up reading the adventures of his favorite superhero, Jay Garrick, the original Flash and acted many of his hero's adventures out with his friend and future actress, Daphne Dean.
He called himself the Flash, a tribute to his childhood idol He briefly considered wearing a costume that would show his face, like Jay had, but decided that it would be best to wear a mask to conceal his true identity.
As the Flash, Barry later became a founding member of the Justice League of America, where he befriended Hal Jordan, the Green Lantern, with whom he had many adventures both with and without the Justice League.
The next day, Barry saved Iris from a stray bullet.
There was no question about it: the freak accident had somehow given Barry superhuman speed!
He graduated in three years with a major in organic chemistry and a minor in criminology.
While a senior, Barry helped the authorities apprehend a bank robber, and he was offered a job as a police scientist for the Central City Police Department Scientific Detection Bureau.
Using his super-speed powers, he taps into the Speed Force and becomes a costumed crime-fighter.Eager to be in the sister city of his childhood hero's home, Keystone City, he accepted the offer.After moving to Central City and getting an apartment with a laboratory in the back, Barry began dating Picture News reporter Iris West, whom he met while examining an apparent murder that she was reporting. That night during an electrical storm, Barry returned to an experiment after a short break.He was an incredible Flash fan, and he knew his aunt's boyfriend was a "friend" of the Flash, so a meeting was arranged.The Flash offered to answer all of Wally's questions, so Wally asked how the Flash had gained his powers of super-speed.
